How to limit the size of the connection method parameter

i connected an fms server like var nc = new netconnection ();
                                                  nc.connect ("rtmfp :/ / localhost: 61018/zy/1", a);
but how restrict the size of the parameter a, assuming that this a set to a 10gb object, or a large byte, i found that the server received. this allows the hacker attacks, is there way to limit the size of this a, i hope that does not exceed 100kb.

rtmfp encodes low-level messages in manner compatible rtmp messages. rtmp messages length-field limited 16mb (24 bits), , there artificial software limit less (approximately 10mb if recall correctly).

 

it should not possible send connect message rtmfp or rtmp server exceeding 10mb.

 

bytearray limited 4gb, , can't serialized amf beyond 512mb (29 bits).

 

also keep in mind rtmfp or rtmp server receive such large message, many bytes must sent somewhere (you).
